Log xy/4 =
log xy - log 4 =
log x + log y - log 4
1/4(2x - 14) = 4
Divide by 1/4. (dividing by a fraction = multiplying by its reciprocal, so ÷1/4 = ×4)
2x - 14 = 16
Add 14 to each side.
2x = 30
Divide by 2.
x = 15
Answer:
$14.80
Step-by-step explanation:
I'm assuming you meant to put 3.20 since $320 a mile would be ridiculous.
C(n)=2.00+3.20n
If n = 4 miles we have:
C(4)=2+3.20(4)
C(4)=2+12.80
C(4)=14.80
So the cost of the taxi is $14.80.
Answer: think A
Step-by-step explanation:
Y=9r, r=r
9r+r=30
10r=30
r=30/10
r=3(Red Sox)
